The premechanical age is the earliest age of information technology. It can be defined as the time between 3000B.C. and 1450A.D. We are talking about a long time ago. When humans first started communicating they would try to use language or simple picture drawings known as petroglyths which were usually carved in rock.
The first power semiconductor device appeared in 1952 with the introduction of the power diode by R.N. Hall. It was made of germanium and had a reverse voltage blocking capability of 200 V and a current rating of 35 A. The thyristor appeared in 1957. power semiconductor device is usually used in commutation mode (i.e., it is either on or off), and therefore has a design optimized for such usage; it should usually not be used in linear operation.
